1.35 g (0.005 mol) of lb was dissolved in 10 ml of N,N-dimethylformamide, and 0.83 g of potassium carbonate was added thereto, and the mixture was stirred for 0.5 and 1:45 g of 2b was added in portions, then, the mixture was heated to 80° C., and stirred for 8 hours. After the reaction was detected by TLC, the reaction solution was poured into 50 ml of saturated brine, and extracted with three portions of ethyl acetate (100 ml) and dried. After desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1˜300 to yield 1.92 g of oily product.

EXAMPLE 4 Synthesis of the Compound 420

1.0 g (0.002 mol) of lb was dissolved in 30 ml of ethanol, and 0.85 g of a 40% aqueous solution of methylamine was added thereto, then the mixture was heated to reflux temperature and reacted, the reaction was stirred for 8 hours. After the reaction was detected by TLC and desolvation, it was purified by column chromatography eluting with petroleum ether: ethyl acetate 1000:1˜300 to yield 0.86 g of oily product.

(1)Testing Examples of Biological Activity

Activity test experiments of the compound of the present invention against adults of Tetranychus cinnabarinus were carried out. The test methods are as follow:

EXAMPLE 8 Insecticidal Activity Test

A certain amount of the original drug was weighed by an analytical balance (0.0001 g). and dissolved in DMF containing 1% Tween-80 emulsifier to prepare a 1% mother liquor, which was then diluted with distilled water for later use.

The insecticidal efficacy was evaluated by a leaf-dipping method with the armyworm as a target and a spray method with Tetranychus cinnabarinus and Aphis craccivora Koch as a target.

Activity test of armyworm

Leaf-dipping method: the target for the test was the armyworm, and corn leaves in an appropriate amount were fully infiltrated in the prepared liquid, then dried naturally, placed in culture dishes with filter papers, inoculated with 3rd instar larvae of the armyworm at 10 heads/dish, and placed in an observation room and cultured at 24˜27° C. the results were investigated after 3 days. A brush was used to touch the insect bodies, and the unresponsive were regarded as dead insects.

Partial test results are as follow:

At a test concentration of 500 mg/L, compounds 1, 49, 50. 55, 65, 68, 71, 114, 115, 131, 163, 191, 195, 209, 210, 212, 262, 263, 272, 339, 358, 404, 407 had a lethal rate of more than 80% on aphids;

Compounds 68, etc at 100 mg/L had a lethalrate of more than 80% on aphids.

EXAMPLE 9: Activity Test of Tetranychus Cinnabarinus and Aphis Craccivora Koch

Spray method: the target for the test was Tetmnychus cinnabarinus and Aphis craccivora Koch, that is, broad bean leaves inoculated with Tetranychus cinnabarinus and Aphis craccivora Koch, respectively, were placed under the spray treatment of Potter spray tower. After the treatment, the Tetranychus cinnabarinus were placed in an observation room and cultured at 24˜27° C.,the Aphis craccivora Koch was placed in an observation room and cultured at 20˜22° C., and the results were investigated after 2 days. A brush was used to touch the insect body, and the unresponsive were regarded as dead insects.

The living pot assay method was adopted, that is, the sample of the test compound was dissolved with a small amount of DMF solvent (the kind of solvent such as acetone, methanol, DMF, etc., is selected according to the solvency of the sample, and the volume ratio of the solvent amount to the spray amount is equal to or less than 0.05), diluted with water containing 0.1% Tween 80, and fotmulated into the test solution with a desired concentration. Cucumber seedlings at leaf period with the same growth period was sprayed evenly with the prepared agent, and aired. Each concentration was one treatment, each treatment was repeated 3 times, a control agent and a water of blank control were set separately. The fresh powdery mildew spores on the leaves of cucumbers were washed and filtered with double gauze to prepare a suspension with a concentration of about 100,000 spores/mL. The samples were inoculated by spraying, the inoculated samples were moved into artificial climate, and relative humidity was maintained at 60-70%, the temperature was maintained at 23° C., after about 10 days, grading investigation was carried out according to the morbidity of the blank control, control effect was calculated according to disease index.

Experimental methods were as follows:

Spray method: the test target was Tetranychus cinnabarinus, that is, broad bean leaves inoculated with adults of Tetranychus cinnabarinus were placed under the spray treatment of Potter spray towers. After treatment, the Tetranychus cinnabarinus was placed in an observation room and cultured at 25˜27° C., and the results were investigated after 48 hours. The brush was used to touch the insect body, and the unresponsive were regarded as dead insects. The test concentrations of the compounds on killing cinnabarin were 50, 25, 12.5, 6.25, 3.125 mg/L.

Egg test: each treated broad bean leave was inoculated with 10 adults of Tetranychus cinnabarinus, and the adults were removed after the eggs were laid for 24 hours. The leaves with eggs were sprayed under Potter spray towers. After treatment, the eggs of Tetranychus cinnabarinus were placed in an observation room and cultured at 25˜27° C. And the test was examined until the eggs under the blank treatment completely hatched out. The concentration of the compound that kills the eggs of Tetranychus cinnabarinus was 100, 50, 25, 12.5, 6.25 mg/L.

Nymph test: broad bean leaves were inoculated with 10 adult mites, and the adults were removed after laying eggs for 24 hours. The eggs were fed in insect rearing room, and when they hatched into nymphs, they were sprayed with a sprayer. After fteatment, the leaves with the nymphs were placed in an observation room and cultured at 25-27°C, and the results were investigated after 48 hours. A brush was used to touch the insect bodies, and the unresponsive were regarded as the dead. The test concentrations of the compound on killing cirmabarin were 5, 2.5, 1.25, 0.625, 0.3125 mg/L.
